Interstate 670 (I-670) is an Interstate Highway in the U.S. state of Ohio that passes through downtown Columbus, connecting I-70 west of downtown with I-270 and US 62 near the eastern suburb of Gahanna. I-670 provides access to Port Columbus International Airport, and intersects SR 315 and I-71 downtown. The section between SR 315 and I-71 is commonly referred to by locals as the "North Innerbelt", with the rest of the innerbelt consisting of SR 315 (west), I-70 (south), and I-71 (east and south).

History
In the late 1970s, the Ohio Department of Transportation was unable to complete the Spring-Sandusky interchange, linking both sections of the highway, due to budget shortfalls and environmental regulations, leaving I-670 the only uncompleted Interstate in Ohio. Two decades passed before work began on the last remaining section, bridging the gap between the two completed sections. Work on this section also included the High Street cap, a cut-and-cover bridge over the highway featuring shops and restaurants. I-670 was finally completed in 2003.
Route description

The south roadway carries the eastbound main lanes and the westbound entrance ramps from I-71 north and SR 3 (Cleveland Avenue), while the north roadway carries the westbound main lanes and the eastbound entrance from US 23 north (4th Street) and High Street.
